Who has information on air compressor operation along with an explanation of its principles?

The commonly used types are screw-type and centrifugal-type; you should choose an air compressor based on the purpose for which you need to compress air, as well as the required pressure and volume of air

It is used to pump air; specifically, it consumes electricity or other forms of energy to draw in free air from the environment and deliver it to a designated location. In the past, there were few options available, but nowadays there are many choices. Besides some standard parameters, high energy efficiency is a key trend

(1) What is the working principle of a screw compressor? 1. Suction process: The suction port on the intake side of the screw compressor is designed to allow the compression chamber to draw in air sufficiently, with the amount of air intake being regulated solely by the opening and closing of the intake control valve. As the rotor rotates, when its tooth grooves reach the opening at the intake side wall, the space within those grooves is at its largest. At this point, the space in the rotor’s tooth grooves is in communication with the free air outside. During exhaust, all the air in the grooves is expelled, leaving them in a vacuum state. When the rotor reaches the intake position, external air is drawn in and flows axially into the rotor’s tooth grooves. Once the grooves are filled with air, as the rotor continues to rotate, the teeth of the male rotor begin to mesh with those of the female rotor, and this meshing gradually becomes complete until the air between the teeth and grooves is sealed off. 2. Compression and fuel injection process: The closed chamber formed by the male and female rotors along with the casing moves toward the exhaust end as the rotors continue to rotate; as a result, the volume of the tooth grooves between the meshing lines and the exhaust port gradually decreases. The gas within these grooves is thus compressed, leading to an increase in pressure. At the same time, lubricating oil is injected into the compression chamber and mixed with the air. 3. Exhaust process: When the mating surface of the rotor aligns with the exhaust port of the casing, the pressure of the compressed air reaches its maximum. The mixture of compressed air and lubricating oil is then expelled, until the tooth grooves are completely separated from the exhaust port; at this point the volume of the tooth grooves is zero, and the exhaust process comes to an end. After that, a new cycle of suction, compression, and exhaust begins.
